PRIETO P., María Isabel; CARRILLO R., Ana Isabel e RODRIGUEZ SUSA, Manuel S.. Preliminary tests of direct microfiltration for purification of surface waters in the Sabana of Bogotá. rev.ing. [online]. 2005, n.22, pp.133-141. ISSN 0121-4993.
A microfiltration lab-scale system was studied as alternative to water purification of three reservoirs from the Sabana of Bogotá, Colombia. The system performance was evaluated based on the efficiency of classic parameters elimination, the flux behavior and the degree of flux recovery after membrane cleaning. Additional tests were made adding CAP to the feeding water. Lower work pressures lead to lower fouling membrane rates and the CAP addition reduced the irreversible fouling. Direct microfiltration system is a potential alternative for superficial water purification, but deeper studies are required to corroborate the process suitability to long term.
